The health check function has multiple critical bugs:

1. The config file parser splits lines by space with maxsplit=1 (line 126), so "timeout client 1234" becomes key="timeout" with value="client 1234". However, this function tries to access keys "timeout client" and "timeout server" which don't exist in the parsed configuration.

2. When the timeout fields are missing (line 33-34), the function prints an error but doesn't return False, allowing execution to continue to line 36 where it will crash trying to access non-existent keys.

3. The check at line 36 cannot handle the idletimeout=0 case. When idletimeout is 0, HAProxyConfigurator sets these lines to empty strings (HAProxyConfigurator.java lines 644-645), which means they won't be present in the parsed config.

The correct approach would be to:

• Check for the "timeout" key, not "timeout client"/"timeout server"
• Extract and parse the timeout values from haCfgSections["defaults"]["timeout"] list
• Handle the case where idletimeout is 0 or "0" by verifying the timeout entries are missing or empty
• Return False immediately when timeout fields are missing (if idletimeout != 0)

The code doesn't handle negative values for idleTimeout. If a user somehow configures a negative value, it would fall through the if-else logic and retain the default timeout values from defaultsSection (50000). Consider adding validation to ensure idleTimeout is non-negative, or explicitly handle negative values in the else clause to make the behavior more predictable.
