Sql Jobs bts_PurgeSubscriptionsJob_Biztalkmsgbox

Hi,

We had some problems during heavy load and after some initial investigation we found that bts_PurgeSubscriptionsJob_Biztalkmsgbox job is the root cause of all the issues.

The above job is causing all the issues and we are getting weird erros like timeout expired, process has been choosen as dead lock victim and ultimately the processing stops

Any ideas
Please let me know

Thanks
