Apache 2.4 Error reading chunk and No Space Left on Device

[clar...@gmail.com]

Seeing the following errors occasionally appearing in our error_log:

[Fri May 22 08:26:45.671865 2015] [http:info] [pid 7008:tid 25] (70014)End of file found: [remote X.X.X.X:80] AH01590: Error reading chunk
[Fri May 22 08:26:45.671986 2015] [proxy_http:error] [pid 7008:tid 25] (28)No space left on device: [client XXX.XXX.XXX.X:26472] AH01110: error reading response, referer: https://REFERRING_URL

Server is being used solely as a reverse proxy, so it is just passing requests through.

Apache 2.4.9 installed on Solaris 10, proxying requests to a Virtual IP which sends the request to IIS web servers. The remote IP listed that is returning the 'End of file found' is the Virtual IP on a Netscalar.

Memory is fine, disk space is fine.

We are trying to upgrade from 2.4 from 2.2. 2.2 does not show these types of error when serving requests.

Any help would be appreciated.

Thanks.

Chris

Snooping around on the AH01110 error, I came across this:

http://mail-archives.apache.org/mod_mbox/httpd-users/201407.mbox/%3CCAKUrXK6X0KOyWKBDs8RG4OX...@mail.gmail.com%3E

"I think it is possible to get that error with proxy when a compressed
response from a backend server is relatively large."

And further in that reply:

"If your log level is higher than info (e.g., error), try something
like

LogLevel error http:info deflate:warn

to see log messages that could pinpoint exactly where the error comes
from."

Seems like some buffer or other is running out of space, and it gives
a slightly misleading "out of disk space" when it possibly should say
"out of space".

Searching on the AH01590 error is mostly useless, but turns up a List
of Errors document which may be of use:

Thanks... Had the LogLevel setting previously set to info, changed it to debug, waiting for the error to appear again.
