tarantool/override/metrics/psutils/psutils_linux.lua:49: bad argument #1 to 'string.split' (string expected, got nil) #526
Description
Just got following error in tests (only once):
tarantool/override/metrics/psutils/psutils_linux.lua:49: bad argument #1 to 'string.split' (string expected, got nil)
Seems a case when file:read() returned malformed string should be handled
