Our new/fresh dovecot imap installation on CentOS (latest from yum repository, which is 2.2.10) is locking up with a panic on a consistent basis and denying service to subsequent clients. The behavior is repeatable. Have spent weeks debugging and trying different configurations with no success.
Specific /var/log/maillog error messages are:
12:06:54 dovecot: auth: Error: talloc: access after free error - first free may be at ../auth/ntlmssp/ntlmssp_server.c:457 12:06:54 dovecot: auth: Error: Bad talloc magic value - access after free 12:06:54 dovecot: auth: Error: PANIC (pid 2570): Bad talloc magic value - access after free
Looks like a bug in the winbind code.
