RecvFrom() continuously returns KErrGeneral in Symbian

[bennylp]

For some strange reason, and on some platforms only, an asynchronous RecvFrom?() will continuously return KErrGeneral. This happens with S60 3rd Edition MR2 emulator on Win2k, but doesn't happen with S60 3rd Edition (not MR2) on WinXP.

Some people suggested that increasing the receiving buffer size should solve the issue (see ​http://discussion.forum.nokia.com/forum/archive/index.php/t-52250.html) but this doesn't seem to be the case. In PJSIP, the PJSIP_MAX_PKT_LEN is used to control the RX packet size and the default is 2000. Increasing this to 4000 doesn't seem to help.
