Bug Description

Hi All,

We have a plone site with ZODB 3.8.3 with large number of objects. Whenever we run a report which processes a large number of objects, we get the following error:

2018-05-04T01:57:12 ERROR ZODB.Connection Couldn’t load state for 0x030c8158

ValueError: invalid literal for int():

If we segregate the report in 5-6 reports we don’t get this error. We have also noticed that the /temp folder size increases very much. Can someone please suggest a solution for this?

Thanks,
Rahul
