[Xymon] scvstatus gives error on version 30, but not on version 28

Thu Mar 5 08:03:48 CET 2020

Hi,

I recently upgraded from version 28 to version 30. Everything works except some Trends pages. These trend pages include a lot of grapics coming from rrd directories with more than 750 rrd's in it. Directories with around 200 work and give no error.

I made a strace with version 30 and gives this for the error:

version 28 gives the next part (not completely):

I'm no c programmer, so can someone look into this error?
