Hi,
I have the same crashes in pop3 with the recent dovecot release 2.2.11
on Fedora 16 x86_64. The log file shows:
dovecot: pop3(usern...@example.com): Fatal: master: service(pop3): child
26735 killed with signal 11 (core dumped)
New mails will be successfully fetched by the client but all the dovecot
files in the users maildir (dovecot.index.log, dovecot.index.cache, ...)
are not being updated anymore.
Here is my backtrace:
-----> start backtrace <-----
