[erlang-questions] fprof problem in 19.1?

[Andreas Schultz]

Hi,

I'm not sure whether if it's my fault or if something wrong with fprof.

Running a trace on rather busy system (trace file is 250MB), I get this error (full output):

Erlang/OTP 19 [erts-8.1] [source] [64-bit] [async-threads:10] [kernel-poll:false]

Eshell V8.1  (abort with ^G)
(ergw-gtp-c-node@REDACTED)1> fprof:trace([start, {file, "/tmp/ergw.trace"}, verbose, {procs,all}]).
ok
(ergw-gtp-c-node@REDACTED)2> fprof:trace([stop]).
ok
(ergw-gtp-c-node@REDACTED)3> fprof:profile({file, "/tmp/ergw.trace"}).

{error,{incorrect_trace_data,fprof,1714,
                             [{trace_ts,#Port<0.692>,send_to_non_existing_process,
                                        {inet_reply,#Port<0.692>,ok},
                                        [],
                                        {1476,206371,694992}}]}}


Any idea what's going on here?
