On one of our (Red Hat 7.3, dual PIII CPU) servers running cyrus-imapd (2.2 CVS as of late September 2002), last night POP3 and POP3S access mysteriously "stopped working". IMAP and IMAPS access are still fine.
Looking at the logs shows things like: Jan 10 02:11:16 aerogram pop3s[17907]: DBERROR db4: 459 lockers Which is, shall we say, unusual. Since October we have seen only very small numbers of "lockers" in these messages. This server has only some tens of email users at present. Only the duplicate and tls db's use berkeley. Attempting to access the server via POP3 gets a connect and then nothing. Access via pop3s gets a connect, the full SSL handshake sequence, then nothing. Restarting cyrus-imapd did not help. cyradm version output is: name : Cyrus IMAPD version : v2.2.prealpha-GRC-RPM-2.2-cvs.20020926 2002/09/26 19:19:16 vendor : Project Cyrus support-url: http://asg.web.cmu.edu/cyrus os : Linux os-version : 2.4.18-17.7.xsmp environment: Built w/Cyrus SASL 2.1.7 Running w/Cyrus SASL 2.1.10 Sleepycat Software: Berkeley DB 4.0.14: (November 18, 2001) OpenSSL 0.9.6b [engine] 9 Jul 2001 CMU Sieve 2.2 TCP Wrappers mmap = shared lock = fcntl nonblock = fcntl auth = unix idle = poll mboxlist.db = skiplist subs.db = flat seen.db = skiplist duplicate.db = berkeley-nosync tls.db = berkeley-nosync We had upgraded cyrus-sasl to 2.1.10, but downgrading back to 2.1.7 did not change this issue. Attaching to one 'connected to but hung' pop3d with gdb shows a backtrace of: (gdb) bt #0 0x420dadf4 in read () from /lib/i686/libc.so.6 #1 0x4002a480 in __DTOR_END__ () from /usr/lib/libsasl2.so.2 #2 0x40024186 in randinit () from /usr/lib/libsasl2.so.2 #3 0x400241cd in sasl_rand () from /usr/lib/libsasl2.so.2 #4 0x40023e3f in sasl_mkchal () from /usr/lib/libsasl2.so.2 #5 0x0804cccb in service_main () #6 0x0805149b in main () #7 0x42017589 in __libc_start_main () from /lib/i686/libc.so.6 (gdb) How can I best troubleshoot this further -- or is a quick fix already known?
