has anyone else run into a problem like this? my build system runs some scripts which depend on the existence of the injectedEnvVars.txt created by jenkins. users reported that that sometimes, some of these files would mysteriously become 0-length. the files had the correct content initially, but somehow hours, days, or weeks after the build, the files became truncated. there was no obvious rhyme or reason to the builds that were affected. sometimes, it'd be one build seemingly struck at random in the middle of a series of builds.
the file system has plenty of space. i also checked the system logs but found no related messages. also, i have found no evidence of any files other than injectedEnvVars.txt getting clobbered this way. to investigate the problem, i started running a cronjob to scan the jobs directory for such files. the cronjob would run every 30 mins and report any "new" truncated injectedEnvVars.txt files. once this cronjob had been running for awhile, i noticed an interesting pattern. that the newly truncated files tended to show only on the cron iterations at 6-hour intervals. (eg, 00:30, 06:30, 12:30, 18:30). later i realized that the jenkins "disk usage" calculation was also scheduled for 6-hour intervals (00:00, 06:00, 12:00, 18:00). as an experiment, i tried shifting the schedule of the disk usage calculation by 3 hours. result: the times when the truncated files appeared, also shifted by 3 hours. my next experiment was to disable the disk usage calculation altogether. no new truncated files have appeared since then. to me the evidence suggests that the jenkins "disk usage" calculation is somehow causing these "random" truncations of injectedEnvVars.txt files. we are running jenkins v 1.607. suggestions? -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.
