I just experienced a similar panic error-out message:
PANIC! : Too many URLs : >99995
I am trying this first:
httrack
A cache (hts-cache/) has been found in the directory That means you can update faster the remote site(s) OK to Update httrack httrack?
Press <Y><Enter> to confirm, <N><Enter> to abort
and I typed Y and press the [enter] key
Guess it's continuing from where it left-off. It is running for the last 15 min now; not sure if I will hit the same error again later.
A quick check the files and size downloaded previously suggested that it did continue from where it left-off.
HTH whoever stumble into this in the future! :)

Update 01: 35min since started and still running.
Observation: some download mark with * at beginning of line and some others mark with numbers: 1497/6451. Guess some new pages added and existing pages got updated.
Update 02: 3hrs taken and about 500MB more downloaded. Tested some missing links/pages are now available offline! :)
