Hi,

Occasionally we seem to have a problem where emails received by Salesforce do not create cases. his causes us a serious issue as requests (orders) from customers will likely be missed. 

We receive a warning by email which states: 

"...The following errors were encountered while processing an incoming email: 

UNABLE_TO_LOCK_ROW : unable to obtain exclusive access to this record..."

What i did for this is:

We have 3 triggers on Case Object, which fires upon case creation for an incoming Email from customers. Put all the code in try catch blocks and write a chatter post in catch block. There by chatter group people will get a chatter post upon any lock error from any trigger. There by we can move that code to batch class and call it in future method. So that, we can remove that lock error.

Does my approach solve this problem?

Any suggestions would be appreciated?
