Just wanted to mention that an upgrade to glibc 2.3.1 (built from Rawhide SRPM's) resolved this problem on our end. So, it is definetly a problem with MySQL<->glibc interaction (if not a bug in glibc itself). |
Description of Problem: mysql-3.23.52-3 seg faults on remote network connects. Using the mysql client, and running mysqld under the debugger. I get this: Program received signal SIGSEGV, Segmentation fault.
