dovecot: imap-login: Panic: Trying to allocate 0 bytes
My ISP had a hard drive crash. After the dust settled, my dovecot installation started failing with the following error every time a client tries to connect:
dovecot: imap-login: Panic: Trying to allocate 0 bytes
My installation has otherwise been stable and rock-solid for years. Both I and the techs at my ISP are stumped. Any advice on how to debug this would be greatly appreciated.
Vital info:
[ron@vm1:/etc/dovecot]$ /usr/sbin/dovecot -n
1.2.15: /etc/dovecot/dovecot.conf
OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.10
log_timestamp: %Y-%m-%d %H:%M:%S ssl_ca_file: /etc/ssl/local-certs/startssl.ca.pem ssl_cert_file: /etc/ssl/local-certs/... ssl_key_file: /etc/ssl/local-keys/... login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login first_valid_uid: 100 mail_privileged_group: mail mbox_write_locks: fcntl dotlock auth default: user: postfix passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: prefetch socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix
I have checked the MySQL configuration and everything seems to be OK there. In fact, I’ve checked everything that I know how to check, and everything seems to be OK. And yet it is not working.
Many thanks, rg
Figured it out. Turned out to be a corrupted ssl parameter file.
