Cannot see any reason for the following error message:
Can't use string ("0") as a HASH ref while "strict refs" in use at get line 109.
my debug out
100 getsnmp result 101 .>"router" 107 sysDescr=>"router" $$myresult{sysDescr}=router; 115 return 116 sysDescr=>router 100 getsnmp result 101 .>"BroadbandVI_5PrNE" 101 .>"A" 107 mtssid=>"BroadbandVI_5PrNE" $$myresult{mtssid}=BroadbandVI_5PrNE; Can't use string ("0") as a HASH ref while "strict refs" in use at get line 109.
Works OK several times, the fails later. The failed command printed at line 108 before execution line 109. Any ideas? Work around?
