if device is having more punches it fails

[alamnaryab]

we have around 20 devices, for some of the I can fetch all punches in few seconds while some are taking too longer to fetch punches.
I also tried to increate max_memery and max_timeout but still it is not returning and server gets hanged.
any idea how to deal with such situation?
1- avoid server getting hanged.
2-read punches in optimized manner when there are many (eg 20k or 40k punches)

Hello!

1. Check the network connection to slow devices. Also I had problem with one device, ZKTeco service checked it and said "device too old and slow, you need new one"
2. Not possible (see getAttendance return empty value #1 (comment)) , if you have a lot of punchng then you can get attendance and clear device very often. (see example Supported Model #25 (comment))

Devices isn't for keep big data and operate fast.
Better store the attendance in fast DB and clear up device :)
