Hi,
I obtain continuosly segmentation fault of processes pop3 and imap, with
version 2.2.10.
This is the error for the pop3 process (but for imap is is the same):
2014-02-10 11:06:22 pop3(xxxxxxx at yyyyyyyy.zz): Fatal: master:
service(pop3): child 23804 killed with signal 11 (core dumped)
This is the kernel log:
Feb 10 11:06:22 pecpop5 kernel: pop3[23804]: segfault at 7fa42a3f4070 ip
