Hi Umesh,
Make sure operations in process 1 are actually terminated by a commit.
You can connect to database as DBA and use system procedures like sp_iqlocks, sp_qtransaction , sp_iqcontext to check current locks and transactions.
Check in related iqmsg file (IQ database error log) to see if an exception prevented the operation in process 1 to finsh properly.
Regards,
Tayeb.
