any body using Solaris8 with postgresql 7.3.3

Hi, all,

I've met a wierd problem on a Solaris 8/sparc box with postgresql 7.3.3:

the server would automatically shutdown after a period of time of not
operating. The log show something like this:

pmdie 2

anybody using this combo ever met this kind of problem?

Any help would be very appreciated.

Thanks and regards
