What's in the bigip.conf on line 893? You can use vi to check this: vi /config/bigip.conf. Then type :893 enter
If it's the beginning of an iRule can you post the iRule? Or if it's the middle of an iRule, can you post that line?
If you're not able/comfortable posting the iRule code verbatim you could open a case with F5 Support on this.
And here's a related solution from AskF5 that may explain the issue:
sol7988: The iRule parser may fail to correctly parse and load an iRule when using the bigpipe load command
