Details: a partition on iSeries 550, V5R3 level, connect jobs to the 400 through this WebService provided by the ASNA data gate product, and IIS is involved in some way.
Problem: Jobs run fine for any length of time, 15 -20 45 - 50 minutes depending on when they are launched until the time on the iSeries hits the top of the hour. At the top of the hour, the jobs end and die off consistently, always at the top of the hour. Like something is resetting, or the resources are taken away, or something else is launching. Very little info to go on but just odd enough maybe someone has heard of or seen a similar issue or event involving the same kind of timeframe.
