Sereal corruption redux?

[dasyurid]

• Plugin version: 1.17
• Perl version: 5.32.1
• Operating system: Ubuntu 20.04.2 LTS

Repeated (multiple / s) errors from Sereal (4.018) of the same type as issue #6.

Example:
Mojo::Reactor::Poll: I/O watcher failed: Sereal: Error: Unexpected tag SRL_HDR_ARRAYREF_4 while expecting a stringish type at offset 2503 of input at srl_decoder.c line 1118 at /opt/perlbrew/perls/perl-5.32.1/lib/site_perl/5.32.1/Mojo/MemoryMap/Writer.pm line 19, line 960.

There are are variety of details in the errors, but all are of the same general form and all trace back to MemoryMap::Writer line 19. "Bad tag", "unexpected end of packet", "bad COPY tag", "unexpected end of input stream", 'No THAW method defined for class 'åE/4#Áªzù�&'', etc. Happy to supply further details if it will be helpful, but this seems to be more effect than cause.

For us in 5.34.0 and Ubuntu 22.04 LTS the problem seemed to go away when we removed an addiitonal route that was matching the route set up with the Status-plugin. The conflicting route was fetched a lot and the expected route was shown, but maybe the plugin one was triggered too?

Unsure if there was some kind of loop going on or too many parallell requests, or if it was a too big stash (with cyclic references) or something like that was causing this.

Seems we suddenly got the error back after all :-/
