This activity is triggered by an Agent1 which runs every 5 secs.Acitivity2 also uses object open by handle on a data page called Page2 of A-B-C. This activity is triggered by an Agent2 which runs every 60 secs.Both object open by handle use lock and ROC (release on commit) features.Though the data pages are named differently in both activities, will this cause a problem in activity2 if activity1 already is having a lock on pzinskey.I have a similar issue causing heap space and server crash. Investigating this and needs your precious inputs.thanks,Jagan Low-Code App Development System Administration ×Close popoverFacebookTwitterLinkedinEmail Copy Link Copied!

If Agent1 has the lock, then an error will occur when Agent2 attempts to obtain a lock.

If you can share some more details, we can suggest,. Thanks.

After exiting the loop, sets property .Pro='No' goes on to do more steps, calls another Activity234 and returns Then does a Commit. Activity2 which runs every 60 secs does the following: Opens a new pageV of class A-B-C Does an obj-browse on pageV to filter the pzinskey with condition .Pro='No' & .Old=null Iterates on the result of pageV.pxResult Create a page-new of pageV2 of class A-B-C (no parameters set) Does obj-open-by-handle on pageV2 with instance handle as pzinskey. Lock and ROC selected. This is the place where the issue happened and logs show that it got stuck. --------------------- What is confusing for me is, in Activity1, the parameter .Old was set to true and .Pro was set to No. When Acitivity2 runs, it browses for .Old as null, but still some how got the same pzinskey. How is this possible. Hope the details are clear for you to answer. Let me know if any thing is not clear.

IN View Profilevanaa PEGA replied to JagannathR8869Could you try obj-save with write now option enabled. So that the property change is committed immediately. After setting .Pro='No', is there an obj-save operation, if not .pro value wouldn't be persisted.
