### What happened?
Reading eight tags every second from a S7_1200 PLC with S7 with version
0.12.0 it works, but with 0.13.0-SNAPSHOT after a while the connection drops
and cannot be restored; it gets stuck in a loop at:
`[plc4x-s7ha-thread-1] INFO

Example code:
public static void main(String[] args) {
initialize();
scheduler.scheduleAtFixedRate(() ->
executeRead(config.getTags()), 0, 1000, TimeUnit.MILLISECONDS);
}
public static void initialize() {
cachedPlcConnectionManager =
CachedPlcConnectionManager.getBuilder().build();
config = Configuration.getConfiguration();
scheduler.scheduleAtFixedRate(() -> executeRead(config.getTags()),
0, 10, TimeUnit.MILLISECONDS);
}
public static void executeRead(List<Configuration.Tag> tags) {
try (PlcConnection plcConnection =
cachedPlcConnectionManager.getConnection(config.getDeviceAddress())) {
if (!plcConnection.getMetadata().isReadSupported()) {
System.out.printf("[%s] Connection does not support
reading%n", LocalDateTime.now());
return;
}
PlcReadRequest.Builder readRequestBuilder =
plcConnection.readRequestBuilder();
for (Configuration.Tag tag : tags) {
readRequestBuilder.addTagAddress(tag.getName(),
tag.getAddress());
}
PlcReadRequest readRequest = readRequestBuilder.build();
PlcReadResponse response = readRequest.execute().get();
processResponse(response);
} catch (PlcConnectionException e) {
System.out.printf("[%s] Connection error: %s%n",
LocalDateTime.now(), e.getMessage());
} catch (Exception e) {
System.out.printf("[%s] Error during PLC read: %s%n",
LocalDateTime.now(), e.getMessage());
}
}
On failure, it creates up to 40 connections, then closes them, and continues
opening and closing connections without establishing a working one.
