Hello guys,

I'm facing problems with PI 2 mini - it sometimes hangs (oh well: may be only network interface hangs) on high network load. (Like sftping very large files).

Is that a known problem?

Have you had a look whether you suffer from overheating?

  1. cat /sys/class/thermal/thermal_zone1/temp
  2. cat  /proc/cpuinfo
  3. dmesg | egrep "killed|Budget"
Copy code

bronco, thanks for reply. Nothing looks like overheating:

  1. cat /sys/class/thermal/thermal_zone1/temp
  2. 39
Copy code

and /proc/cpuinfo is unsuspicious, too.

The attached console told me that

  1. 64 bytes from 192.168.0.1: icmp_req=66 ttl=64 time=65.4 ms
  2. ping: sendmsg: No buffer space available
  3. ping: sendmsg: No buffer space available
Copy code

while I was using X via XDMCP, and after some pause it resumed working.

The question is still the same - what's that and how to fix it?

Also, I see the following in messages
