Comment 9 for bug 528965

1.) Yes, it was the same SW and HW, I just replaced MySQL server.

2.) No, I wasn't doing any tests. Only MySQL server is crashing and I'm experiencing this problem o 3 different servers. The server which is under biggest load is crashing more often. The one which crash while restoring DB from dump is under very low load and I got crash only two times on it (the second one was with that dump). This is why I think that crash is related to the load of MySQL server.

Yesterday I changed configuration based on Arjen Lentz suggestion:
tmp_table_size = 32M
max_heap_table_size = 32M

This is the only change I made and now I cannot tell if it will make any difference.
