Dovecot 2.3.7.2 lucene segfault and coredump

[Domenico Pastore]

Hi,

do you have the same problem with lucene?

I collected a strace on the dovecot process during indexing:

[pid 31339] open("/lib64/libz.so.1", O_RDONLY|O_CLOEXEC) = 4


All missing libs are in "/usr/lib64" and no to "/usr/lib64/dovecot"

Can you help me?

Br,

Domenico
