Hi,

After enabling lmd, we have observed that checks in Thruk not getting executing further and got stuck at the same time.

We have observed that below entries in lmd.log file

Please find below lmd.ini file

OMD[sample@xxxx]:/tmp$ cat thruk/lmd/lmd.ini
Listen = ['/omd/sites/sample/tmp/thruk/lmd/live.sock']
LogFile = '/omd/sites/sample/tmp/thruk/lmd/lmd.log'
LogLevel = 'Debug'
[[Connections]]
name = 'sample'
id = 'ahedf'
source = ['/omd/sites/sample/tmp/run/live']
OMD[sample@xxxx]:/tmp$

After restarting the OMD services, again the checks getting executed.

Kindly advice what are the possible reasons for the error slow query finished after 9.641389903s, response size: 228 B.
