The hard bit can be detecting that the application has failed. Just relying on the output from a single "ps" command is not safe because a busy system may give a blank or incomplete response to a "ps" command.
To paraphrase Corona688 there is no harm in installing a workaround while you find and repair the root cause ... or determine that the root cause cannot be repaired.
If for example you have a client-server application running on an unreliable network (like the Internet) there is a good case to configure a client retry mechanism backed with a carefully-designed automatic client restart combined with a matching dead-session cleanup in the server.

sasl_client_start
sasl_client_start(3) SASL man pages sasl_client_start(3)
NAME
sasl_client_start - Begin an authentication negotiation
SYNOPSIS
#include <sasl/sasl.h>
int sasl_client_start(sasl_conn_t * conn,
const char * mechlist,
sasl_interact_t ** prompt_need,
const char ** clientout,
unsigned * clientoutlen,
const char ** mech);
DESCRIPTION
sasl_client_start() selects a mechanism for authentication and starts the authentication session. The mechlist is the list of mechanisms
the client might like to use. The mechanisms in the list are not necessarily supported by the client or even valid. SASL determines which
of these to use based upon the security preferences specified earlier. The list of mechanisms is typically a list of mechanisms the server
supports acquired from a capability request.
If SASL_INTERACT is returned the library needs some values to be filled in before it can proceed. The prompt_need structure will be filled
in with requests. The application should fulfill these requests and call sasl_client_start again with identical parameters (the prompt_need
parameter will be the same pointer as before but filled in by the application).
mechlist is a list of mechanisms the server has available. Punctuation is ignored.
prompt_need is filled in with a list of prompts needed to continue (if necessary).
clientout and clientoutlen is created. It is the initial client response to send to the server. It is the job of the client to send it over
the network to the server. Any protocol specific encoding (such as base64 encoding) necessary needs to be done by the client.
If the protocol lacks client-send-first capability, then set clientout to NULL.
If there is no initial client-send, then *clientout will be set to NULL on return.
mech contains the name of the chosen SASL mechanism (on success)
RETURN VALUE
sasl_client_start returns an integer which corresponds to one of the following codes. SASL_CONTINUE indicates success and that there are
more steps needed in the authentication. All other return codes indicate errors and should either be handled or the authentication session
should be quit.
