Ladies and Gentlemen:
I am getting below errors and therefore the user sessions terminate causing
business impact...Can some one who is expertise already in this advice at
120513 8:19:45 [Warning] Aborted connection 1167257 to db: 'iib' user:
'iibuser' host: '18.104.22.168' (Got timeout reading communication packets)
OS version: RHEL 5.3
DB version: MYSQL 5.1
Table involved in the DB is of type : inndoDB
Background : This is an online exam registration site DB and the concurrent
connex invariably reaches to 200 for 500 users which should not be the case.
Ideally the concurrent connex must be <10.
Normally , we run truncate table before the exam starts up.
A similar setup(in terms of DB/OS/config etc ) works fine which is actually
DR at different site.
PS: Network segment between web and DB tier has been thoroughly checked and
seems to be fine.
Thanks a ton!
