I know it is a bad problem description, but that's all I can tell right now -- 3.23.52 sometimes goes into deadlock under heavy load.
Heavy load means approximately 400 queries/second, for extended periods of time. This is a web application backend. There is nothing special about the database, except may be the number of indexes on one table -- it currently has 26 indexes on different integer fields. Biggest table in terms of number of rows is about 100 thousands rows, and one smaller table has blob field that holds data chunks up to 100k each. Any suggestions how to approach the problem? How and what to test? It happens randomly, can work for a day or two with no problems and then hang three times in one hour. And obviously I can't reproduce it in my test environment however hard I stress test it. The system is Linux 2.4.18-3, stock redhat 7.3 on 1.1GHz Athlon with 1 Gb RAM.
