DLLHost.exe pushing CPU to 50-100%
Posted on 2002-05-19
This is a website running for 2 years with VB ActiveX DLLs COM copmponents. From one day to another, after having running fine for 2 years, it became to be unstable. From times to times (about 5 times a day), it would either be very slow, or returning a 500 IIS Internal Error. When this happen, the DLLHost.exe referenced by the concerned website uses 50% of the CPU (it never went above 10% before we begin to have the problem), and sometime just 100% consuming all machine ressources.
I guess that could either be an OS issue (maybe security patches that has this secondary effect) or a strange leak or pb with my DLLs that sundenly wake-up, but those have been running fine before for a long time... Another important point is that the website had no significant activity increase at the time this begun to happen.
Thanks in advance for your useful help :o)
