Hi Raj,

 

Most likely, you're performing a SOQL statement within a loop, while looping through the records in the Trigger.

This works fine for single record updates, but you'll get into trouble when doing bulk updates/uploads through the API.

 

For more info on how to avoid this anti-pattern, see e.g. http://www.salesforce.com/us/developer/docs/apexcode/Content/apex_patterns_bulk.htm

 

Hope this helps.
