[Xymon] Trends graph limit

[Mario]

Hello Jeremy,


The fix you have applied was just change line 213 in
xymon-4.3.30/web/svcstatus-trends.c

from
                                SBUF_REALLOC(rrdlink, rrdlink_buflen +
strlen(partlink) + 4096);
to

 SBUF_REALLOC(allrrdlinks, allrrdlinks_buflen+strlen(onelink)+4096);

and recompile?



Thanks & regards,

Mario
