Error 19: Connection Reset

[avhz]

Hi :)

Is there some way to get additional information on what is causing the error when getting the following error in $data:

'errorValue' 19 (Connection reset)

This error means that the connection has been severed. At this point no more information is available.

It could be because the daemons have been reset before the mirai has resolved, e.g.

library(mirai)
daemons(1)
m <- mirai(Sys.sleep(2))
daemons(0) # reset daemons before `m` has resolved
m$data
#> 'errorValue' int 19 | Connection reset
info()
#> NULL

^{Created on 2025-10-14 with reprex v2.1.1}

Or if the daemon itself has crashed, e.g.:

library(mirai)
daemons(1)
m <- mirai(q()) # simulate a crash
call_mirai(m)
m$data
#> 'errorValue' int 19 | Connection reset
info()
#> connections  cumulative    awaiting   executing   completed 
#>           0           1           0           0           1

^{Created on 2025-10-14 with reprex v2.1.1}

In the former case, info() would return NULL, in the latter the number of 'connections' would show as less than the 'cumulative'.
