Sporadic selftest failure in fty_mc_server.c:504

[jimklimov]

Sometimes our memcheck tests (with and without DRFATS) fail with lt-fty_metric_compute_selftest: src/fty_mc_server.c:504: fty_mc_server_test: Assertion (lots of expanded macros) failed which boils down to

fty-metric-compute/src/fty_mc_server.c

Line 504 in d46b87f

assert (streq (fty_proto_value (bmsg), "50.00"));

not finding a "50.0" in "realpower.default_min_1s@DEV1".
