Looks like the same problem I have... (see "Yet another strange SA
timeout" mail).

I'm currently trying to reproduce with more traces to check where it's

Just to know : what kind of a setup do you have ? (sendmail, mcafee... +
versions used). Characteristics of the machine you use (CPU,RAM...)

Thanks !
