I'm building a chm and pdf file using the commandline with /q /g /y switches. The command is invoked from TeamCity if that matters. Occasionaly the chmprocessor process just seems to hang and doesn't do anything anymore, the only thing I can do then is kill the process. Do you have any idea what could cause this? I cannot reliably reproduce the issue, just that 1 out of 20 builds or so it happens.
