Aborted connections

[Jaap de Heer]

Hi,

We've recently upgraded our 2 mysql servers from 3.22 to 3.23.36,
and since then we occasionally get errors like the following in
the servers' error logs:

010527 21:01:26  Aborted connection 461457 to db: 'clantsf' user: 'tsf' host:
`pride.gamepoint.net' (Got an error reading communication packets)

We've upgraded the client machines from 3.22 to 3.23.32 (the
version that comes with PHP 4.0.5) assuming it was a version
conflict, but this doesn't seem to make any difference.
This only happens once in every 1000 connects or so.
It happens to connections from all client machines.

The server machines run FreeBSD 3.5-STABLE and 4.2-STABLE on
Intels. Both the mysqlds were compiled from source.
The client machines are one Sparc running SunOS, and a few Intels
running RedHat 6.2, with kernels 2.2.19 and 2.4.3.
The connections are made by PHP scripts running on Apache 1.3.19
with PHP 4.0.5, using persistent connections.

Does anyone know what the problem might be, or how I can find out?

Thanks a lot,

Jaap de Heer
