esr has asked for the
wisdom of the Perl Monks concerning the following question:
I have a Perl program running in Windows XP which interfaces with Excel using the WIN32::OLE stuff. The program has been running for a long time and I have made no changes to it recently. When I tried to run it today the program terminated with a SIGALRM for no apparent reason. I am not using any function (that I am aware of) that would precipitate this signal. What is more confusing is that this is only happening on one of our two machines. The program continues to run fine on the second one. The only change to our systems in the last few days was changing our DSL ISP. The configuring of the DSL modem (and router) was done on the machine which is getting the SIGALRM now. The configuration was done using the Yahoo Install Manager which is not installed on the other machine. This may be a total red herring but that is the only change I can think of that was done on one machine and not the other. Has anyone encountered this spontaneous SIGALRM condition and can help me identify what is causing it?
