Re: [ts-7000] TS7800 hiccups around 6:28am everyday

["Eric Robishaw" <>]

Thanks for the heads up on that.  I'm doing data acq via serial port as well, so that's good to know.

Which model TS device do you have, and which serial port are you using? Makes a difference, b/c on the 7800, for example, COM1 & 2 (ttyS0, S1) are handled by the UART whereas the others (ttts0-10) are controlled by the FPGA.

Howdy All!

I have a data acquisition program reading the serial ports on the
TS-UARTS. and everyday around 6:28am, the program has a hard time
getting any data off the serial port.

Has anybody had this issue?

I think I finally figured out what is causing the problem.

The scripts in cron.daily run at 6:25am. The main things that seem to
cause the problem are the find and man-db scripts which search the
filesystem.

Could there be a conflict between the NAND driver and the serial
driver?? I thought this issue was resolved in the jun10 release.

If you want to reproduce this problem, try reading from the serial
port and running: run-parts --report /etc/cron.daily

Thanks!
Rob
