Sorry for top posting, but I have no additional info on this. BTW I need to refresh the question as I have tried squat, and I'm biting the dust with the already known problems ( "Corrupted squat uidlist file" or "Panic: file squat-trie.c:" ).
Is there some pointer on where/how to find assist on fts-lucene to keep on analisys for this problem on sparc ?
T.I.A.

Looks to me like memory corruption, which is just about impossible to debug if you don't have valgrind or a similar tool (and I don't think Solaris has any such free tools).
Yes, you're right. There aren't ( already packaged ) tool for valgrinding or similar.
Do you happen to get any other crashes where it doesn't crash in malloc code? You showed previously that it was crashing with SIGBUS somewhere.
For what I can see, form dovecot.log I have a couple of error: Apr 08 12:02:18 indexer: Error: Indexer worker disconnected, discarding 1 requests for xxxx Apr 08 12:02:18 imap(xxxx): Error: indexer failed to index mailbox INBOX Apr 08 12:02:18 indexer-worker(xxxx): Fatal: master: service(indexer-worker): child 27242 killed with signal 11 (core not dumped) Apr 08 12:02:19 indexer-worker(xxxx): Error: lucene index /home/xxxx/Maildir/lucene-indexes: IndexWriter() failed (#1): Lock obtain timed out Apr 08 12:03:46 indexer: Error: Indexer worker disconnected, discarding 1 requests for xxxx Apr 08 12:03:46 imap(xxxx): Error: indexer failed to index mailbox INBOX Apr 08 12:03:46 indexer-worker(xxxx): Fatal: master: service(indexer-worker): child 27445 killed with signal 10 (core not dumped) Apr 08 12:06:57 indexer: Error: Indexer worker disconnected, discarding 1 requests for xxxx Apr 08 12:06:57 imap(xxxx): Error: indexer failed to index mailbox INBOX Apr 08 12:06:57 indexer-worker(xxxx): Fatal: master: service(indexer-worker): child 27761 killed with signal 11 (core not dumped) Apr 08 12:08:33 indexer: Error: Indexer worker disconnected, discarding 1 requests for xxxx
Here a couple or more of gdb"ed" process, but tied to SEGV ( I almost suspect that when gdbing I always catch a SEGV ) :

Here a couple of ( probably ) interesting stuff :
root # grep "signal 10" /usr/local/dovecot/var/log/dovecot.log |wc 33 284 2308 root # grep "signal 11" /usr/local/dovecot/var/log/dovecot.log |wc 69 549 4457 root # grep "Lock obtain timed out" /usr/local/dovecot/var/log/dovecot.log |wc 74 420 3976
Thus, 74 times of 102 seems to be tied to "IndexWriter() failed (#1): Lock obtain timed out" ( which I don't really understand, or at least I have not enough comprehension of code to understand). The path where lucene try to get a lock is not NFS, but is an automount on the same machine ( no NFS then ).
It seems that the "Lock obtain timed out" happens every time I read a message with the MUA.
This error ("Lock obtain") happens every time I read a message from my MUA, I think it's due to the indexing process running on READ imap command:
Apr 08 15:18:13 indexer: Error: Indexer worker disconnected, discarding 1 requests for xxxx Apr 08 15:18:13 imap(xxxx): Error: indexer failed to index mailbox INBOX Apr 08 15:18:13 indexer-worker(xxxx): Fatal: master: service(indexer-worker): child 18171 killed with signal 11 (core not dumped) Apr 08 15:18:15 indexer-worker(xxxx): Error: lucene index /home/xxxx/Maildir/lucene-indexes: IndexWriter() failed (#1): Lock obtain timed out
When searching, instead, get the "Lock timeout" followed by another error:
Apr 08 15:11:37 indexer: Error: Indexer worker disconnected, discarding 1 requests for xxxx Apr 08 15:11:37 imap(xxxx): Error: indexer failed to index mailbox INBOX Apr 08 15:11:37 indexer-worker(xxxx): Fatal: master: service(indexer-worker): child 17438 killed with signal 10 (core not dumped) Apr 08 15:11:38 indexer-worker(xxxx): Error: lucene index /home/xxxx/Maildir/lucene-indexes: IndexWriter() failed (#1): Lock obtain timed out Apr 08 15:11:51 indexer: Error: Indexer worker disconnected, discarding 1 requests for xxxx Apr 08 15:11:51 imap(xxxx): Error: indexer failed to index mailbox INBOX
In both case the signal ( 11 or 10, SEGV or SIGBUS ) it's indifferent ( sometimes is 10 sometimes is 11 ).
Hope I've been able to explain, as my english seems to get worst every time ;)
