I try to use option "mmap_disable=yes", but in dovecot logs same messages:
"mail_index_lock_fd() failed with 
file /var/mail/sam-butyrev.lk/dovecot.index.log: No locks available\
..."

In syslog such messages:
kernel: lockd: cannot monitor ip_address_nfs_server
kernel: lockd: failed to monitor ip_address_nfs_server

nfs server Solaris 9
nfs client linux slackware 10.1 with kernel 2.4.29
Sory for my english.
