Comment (by warpme@…):
Hi,[[BR]]
After week of heavy stress tests I'm happy to report that if I optimize
mysql query caching with:[[BR]]
"Do not cache results in or retrieve results from the query cache"[[BR]]
system works stable. Test scenarios, results I will post on relevant to
ticket9773 thread on dev-list as I think this ticket and 9773 have common
root cause related to mysql running on ArchLinux.[[BR]]
Situation where mysql query caching with:[[BR]]
"Cache all cacheable query results except for those that begin with SELECT
SQL_NO_CACHE" and [[BR]]
"Cache results only for cacheable queries that begin with SELECT
SQL_CACHE"[[BR]]
are giving deadlocks is still strange for me as issue is with 3 diferent
mysql versions and 4 full system upgrades within quite long periods of
time (so almost all key OS components are changed).
I think both tickets can be closed with status invalid.[[BR]]
Big thx for Your help !
