[Dovecot] pop3 proxying error

7 Aug 2012


      Hi Timo,
I've got some errors with pop3 proxying and dovecot 2.1.9
I's occured on the proxy side:
Aug  7 13:16:47 dev1 dovecot: pop3-login: Fatal: master:
service(pop3-login): child 23046 killed with signal 11 (core dumped)
Server side shows no error, and runs the same dovecot version.
Thanks for your help.
Best regards
Tonio Buonaguidi
