The only documentation I could find is from the mailing list archives - other people have had problems - serious ones - I had them as well. Some of the others have tried the ecommened patch set for solaris 7 and have had some success - but I have tried everything (well almost) and the only thing that has worked is a complete re-install with solaris 8. > > Did yu find any documents on the web substantiating this as a 'known > problem'? > As I said the guys at Sun will not own up - so to speak, but they say - unofficially - that there "might be something there" > I really appreciate your help, I just cannot make a decision to move to > Solaris 8 on our qmail boxes based on one response. > > Thanks you very much for your help.

A little background: qmail 1.03 running on a pentium 166MMX with 64MB ram and a 2GB HDD runnnign redhat 6.2 - being hit by postal with about 3000 - 6000 concurrent SMTP connections - drops about 15% of the connections. and after the onslaught - clears all the smtp and queue processes. A Enterprise 250 with 512MB ram 2 300Mhz CPU's and 50GB HDD running solaris 7 - running the same postal paramaters - chewed up all the ram and droped 90% of smtp connections after 1 hour!!!!! After re-install of Solaris 8 - same setup as before the sparc machine handled 30000 concurrent smtp connections and droped 10% of them. after the onslaught it cleared all the smtp and queue processes cleanly... it also used only 300MB of ram!!! I converted the E450 and 4500 sparc machines and performance went thru the roof!!! I have done extensive testing - and also installed Iain Patersons mysql patch - which improved things even more (after a few hassels :)) I can try and find the docs and papaerwork - but try searching on the mailling list archive for sparc7 and process hanging... Best of luck Tonino
