OK, the problem doesn't occur with --skip-locking. Still, I don't believe this to be a lockd problem as the partition mysqld is working on is a local ext2 fs. lockd isn't even running on the test system (no nfs). So, this leaves either (in no particular sequence): 1. a mysql problem 2. a glibc 2.2

Hi, first of all: the deadlock happened again today, this time with no slave running so it isn't a replication issue. It seems we're getting closer as when I did run 'show processlist', the pending query was (excerpt from output): 1666logreader 10.1.1.4syslog Query 114 Se
