Out Of RPC Cache Error

[Chewie71]

We have a few users reporting these "Out of RPC Cache" errors. Seems to affect multiple browsers. I don't see any related open bugs in Bugzilla...nor have I seen any recent threads on this.

The following is an email I got from another support person. I had him use Firebug to try and get more info....not sure if this is helpful or not though. It seems to be occurring a lot for this user when they are working with the minical.

Well, it went nuts again today while she was trying to use the calendar. I would say around 8:30 give or take and it's still Sharon I'm working with. Firebug was putting a new entry about every three seconds. I didn't see any way to export so I just tried to copy somethings down in hopes that something helps:

This is the actual Zimbra error she gets:
Out of rpc cache

Method: ajxrpc.__getFreeRpcCtxt
msg: out of RPC cache
code: ajxException.out_of_rpc_cache
---
This is the Firebug general error report. Below is the "body" of the error:
Post https://zimbra.wiu.edu/service/soap/...waylistrequest
{"Header":{"context":{"session":{"id":"12264680"," _content":"12264680"},"change":{"token":247144},"_ jsns":"urn:zimbra"}},"Body":{"IMGatewayListRespons e":{"service":[{"type":"yahoo","domain":"yahoo.wiu.edu"}],"_jsns":"urn:zimbraIM"}},"_jsns":"urn:zimbraSoap" }
---
Since I was having a hard time copying the expanded information, I just wrote down some subjects so to speak:
ImgGetRosterRequest
BatchRequest

I tried the send option on the Zimbra error. I'm not sure if it sent anything but, I thought it couldn't hurt.

What OS is the user using ?

[Chewie71]

It's happening to multiple users, all using Windows XP SP3.

It's occurring in IE and Firefox.

Does it clear if you do the following on a workstation

netsh interface ip delete arpcache

This is happening to me as well, I stepped out for a meeting and when I came back Safari had the pop up that said "Out of RPC Cache"

Is there a Zimbra knob that we can adjust?

Jesster, whats up with this error? wonder whats causing this. I read this has been resolved in previous releases like in 5. I got one in 6.0.9. Uxbod, can you comment on this too? Thanks.

I think this is the bug that is tracking this issue...

Thanks chewie. So its pretty much vague whats causing this. Is this AjxRpcRequest a request to server from browser? Or some function that a browser is failing to execute.

Maxxer, thanks. The report says ..

Occured on IE7 and IE8. When setting ?dev=1, the error's gone. After removing
it, the error's there again.

I tried manually setting AjxRpc.__RPC_COUNT to 0, but after a small amount of
time, the error's there again.

Where exactly? the ?dev=1 and AjxRpc._RPC_COUNT to 0 fix.
