I too saw the similar error in Sun Fire T2000 with ubuntu 6.10, mysqld mysqld: pthread_mutex_lock.c:108: __pthread_mutex_lock: Assertion `mutex->__data.__owner == 0' failed.
and also with pthread_mutex_lock used programs in, pthread_mutex_lock.c:80: __pthread_mutex_lock: Assertion `mutex->__data.__owner == 0' failed. ##############WORKAROUND#################### These errors are not seen with ubuntu6.06 release (I downgraded the libc with ubuntu 6.06 libc package-libc6-sparcv9v_2.3.6-0ubuntu20_sparc.deb and able to run mysql and other multithreaded programs without this error) -- get libpthread assertion on multicore CPU https://launchpad.net/bugs/69831 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
