Dave didn't mention that this did not happen under R3.13.7 with the same hardware.

Subject: some of my scan tasks are not being processed because of long delays.
Has anybody seen this before? The delay on one of my scan tasks is 413.2 days. This happens on different tasks on different reboots. This is the SNS timing system, with hardware time support. The driver does not change the vxWorks clock. TSInit gets called before IOCInit, from inside the driver that supplies the time. This seems to happen right at bootup. It has happened on a development system as well as the production system. I went down a wild goose chase thinking one my drivers was malfunctioning before I noticed that some unrelated PVs were never updating.
0x7ffffffff=2147483647, I think the taskDelay call must have gotten a 0 or a negative number. The IOC has been up about a day.
Epics version R3.14.4 VxWorks T202 - kernel similar to Andrew's APS version.
