I'm running the 4.8 series as well and unfortunately we have a lot of custom code in the server portion that we'd need to break out if we were to upgrade IC at this point. We are doing a complete site rewrite that is based off of 5.3.x, so we are trying not to do two upgrades if possible. We also cannot run in High traffic mode to see if the traffic mode is part of the problem because in low and high traffic mode we get double charges and sendmail/pgp can fail. Jeff and John have you tried high or low traffic mode to see if the issue goes away in those modes? > > I don't think that the issue is anything to do with my Virtual Server > > environment, but I thought I better throw it into the mix. > > On my side, the issue has spanned multiple physical servers with > completely different hardware and multiple versions of linux and debian. > > > Jeff We've run IC on about 10 systems over the years. The server I question has been up for about 3.5 years and has been running mod_interchange for the last year or so and has not experienced this problem up until 1 week ago. It's strange that a server would run solid all this time then all of a sudden start exhibiting this behavior. -Ron _______________________________________________ interchange-users mailing list suppressed http://www.icdevgroup.org/mailman/listinfo/interchange-users
