 Posted: Fri 21 Mar '14 17:46 Post subject: Apache 2.4.9 needs more time for syncing |
 |
|
Working condition: Server 2008 R2
Server: Apache 2.4.9 (Win32-VC10) as reverse proxy - same configuration as before
Since the change to apache 2.4.9 we discover 5 log-entries for one sync-process via mobile device where before (2.4.7) there have been only 3 entries for the same sync-process with the same device. Besides this it takes a bit longer.
Do someone else have discovered the same phenomenon?
And what is the reason?

Reading the changelog i guess it could be related to:
| Code: | *) WinNT MPM: If ap_run_pre_connection() fails or sets c->aborted, don't
save the socket for reuse by the next worker as if it were an
APR_SO_DISCONNECTED socket. Restores 2.2 behavior. [Eric Covener] |
Because we use
| Code: | | SetEnv proxy-initial-not-pooled |
for some special locations it sounds possible that the now changed behaviour in combination with the variable leads to a re-initialization of the socket. That could cause two more log entries ...
Can someone shed some light on this? |

| how do the requests/responses differ? Adding two wouldn't make sense unless 2 of the original 3 are failing catastrophically and being retried by the client. |

First of all the 5 entries look very similar.
Besides this i am not sure why it has been three all the time before and if it is related for example to the sync-process of mail, the calendar and tasks. The devices are iPhones which are working fine, but who knows what IOS is doing respectively how a sync is running exactly?!

I can do two things:
1. setting log debug level and have a close look at the log
2. testing without the sentenv parameter
Thanks for helping/asking! |

Please stop any examinations!
The complete log from yesterday does not show any further anomalies.
Don't ask me what it was, but as long as it does not appear again, i would not do a research - it may be connected to the vm-ware environment (which gets a reboot every night) or to whatever.
Thanks again for helping/asking! |
