Version-Release number of selected component (if applicable):


How reproducible:


I'm attaching the same reproducer as for the bu 1310582

Steps to Reproduce:


1. setup mod_cluster and deploy the sample app
2. run the test script, which curl to the sample app. 
3. Observe access and error log

Actual results:
we see around 10 calls after the error, getting 503 while, they should go through

Expected results:

After the broken call, all subsequent unbroken calls should return 200 status
Actual results:
