[Freeswitch-users] Lock wait timeout exceeded; try restarting transaction

Fri Jul 26 22:44:41 MSD 2013


I  made the change in odbcinst.ini not odbc.ini.



# Driver from the mysql-connector-odbc package

# Setup from the unixODBC-libs package

[MySQL]

Description     = ODBC for MySQL

Driver          = /usr/lib/libmyodbc3_r.so

Setup           = /usr/lib/libodbcmyS.so

Driver64        = /usr/lib64/libmyodbc3_r.so

Setup64         = /usr/lib64/libodbcmyS.so

UsageCount      = 1 ß also added this like as per the wiki

FileUsage       = 1

Threading       = 0 ß-  added this line as per the wiki



So far so good.

Thanks. I’ll give it a try and let you know. FYI, I had it happen on 1.2.9
and 1.2.4_lastest tarball.

I saw this problem several times in my Dev environment. No calls ... Only
two registrations.



But after I add threading=0 in odbc.ini , I never see this problem again.
Also I am using most recent version of freeswitch



I am interested into know why this happening even no activity in mysql. I
have lots of resources in the machine.

Run 'SHOW ENGINE INNODB STATUS\G'



What does it show in the latest deadlock section?

Switch - 2 Quad Core / 24 GB Memory / 15RPM SCSI , DB - 2 Quad Core / 24 GB
Memory / 15RPM SCSI . Switch and DB connected through a cross over cable
directly. I do not think this related to a environment issue.

The error is the actual MySQL error, so yes it's definitely a lock timeout.



This means two different queries were trying to access the same data at the
same time. Normally one'll wait until the other is finished, but if it
waits too long you get the lock timeout error.



It can be caused by a query taking too long, or a transaction modifying the
data but then taking too long before commit. To avoid that make sure MySQL
is tuned correctly. Good indexes on the tables and good sizes for the cache
buffers.



Make sure you're using a proper index for the delete operation, I'd also
avoid ORs if possible.



The query is part of mod_sofia, so isn't modifiable. Having a
KEY(hostname,expires) on sip_dialogs may help though if it doesn't already
exist (check with SHOW CREATE TABLE sip_dialogs).



Avoid accessing sip_dialogs from any of your own code to minimise the
number of things that might block each other.
