When trying to empty the recycle bin of one of my portals I got this error:

A critical error has occurred. Transaction (Process ID 79) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.

then after reloading the page everything was still listed in teh pages and modules section. I tried to empty the trash again and got this:

A critical error has occurred. Object reference not set to an instance of an object.

what is odd is that I cleared the recycle bin for 3 other portals on the same instance with no issues at all. Any ideas?

please check file permissions and make sure, no other process (backup, AV, indexer) is interfering file access.

 It could be a backup process... I am not sure. This only happens on portal that have a large ammount of data in the recycle bin...

2 Questions:

1. If this is timing out and not completing and then failing... can I increase the timeout function?

2. Can I limit the ammount of items that are placed in the recycle bin? like 20 modules and 20 pages?


Thanks.
