public static string Prefix(SessionID sessionID)

        {

            DateTime utcnow = DateTime.UtcNow;

 

            string timestamp = (utcnow.Year.ToString().Length == 2 ? "20" + utcnow.Year.ToString() : utcnow.Year.ToString());

            timestamp        = timestamp + "-" + (utcnow.Month.ToString().Length        == 1 ? "0"  + utcnow.Month.ToString()       : utcnow.Month.ToString());

            timestamp        = timestamp + "-" + (utcnow.Day.ToString().Length          == 1 ? "0"  + utcnow.Day.ToString()         : utcnow.Day.ToString());

            timestamp        = timestamp + "_" + (utcnow.Hour.ToString().Length         == 1 ? "0"  + utcnow.Hour.ToString()        : utcnow.Hour.ToString());

            timestamp        = timestamp + ""  + (utcnow.Minute.ToString().Length       == 1 ? "0"  + utcnow.Minute.ToString()      : utcnow.Minute.ToString());

            timestamp        = timestamp + ""  + (utcnow.Second.ToString().Length       == 1 ? "0"  + utcnow.Second.ToString()      : utcnow.Second.ToString());

            timestamp        = timestamp + "." + (utcnow.Millisecond.ToString().Length  == 1 ? "00" + utcnow.Millisecond.ToString() : (utcnow.Millisecond.ToString().Length == 2 ? "0" + utcnow.Millisecond.ToString() : utcnow.Millisecond.ToString()));

            

            System.Text.StringBuilder prefix = new System.Text.StringBuilder(timestamp+"_"+sessionID.BeginString)

                .Append('-').Append(sessionID.SenderCompID);

            if (SessionID.IsSet(sessionID.SenderSubID))

                prefix.Append('_').Append(sessionID.SenderSubID);

            if (SessionID.IsSet(sessionID.SenderLocationID))

                prefix.Append('_').Append(sessionID.SenderLocationID);

            prefix.Append('-').Append(sessionID.TargetCompID);

            if (SessionID.IsSet(sessionID.TargetSubID))

                prefix.Append('_').Append(sessionID.TargetSubID);

            if (SessionID.IsSet(sessionID.TargetLocationID))

                prefix.Append('_').Append(sessionID.TargetLocationID);

 

            if (sessionID.SessionQualifier.Length != 0)

                prefix.Append('-').Append(sessionID.SessionQualifier);

 

            return prefix.ToString();

        }

My workaround is to use custom StoreFactory which writes to DB instead of FileStoreFactory. Hope that'll help.

I'm not aware of a workaround, aside from simply shutting the app completely.
