> During read_while_writer scenario, writer checks if the write VC is closed or the first fragment is completed to try and obtain the write VC's mutex. The writer keeps retrying (unbounded) with 100 msec intervals until either of this occurs. Currently, these retries are unbounded and since they occur nested within the *proxy.config.http.cache.max_open_read_retries*, they sort of cancel out the *proxy.config.http.cache.max_open_read_retries* setting. Opening this jira to add a bound on the number of such internal retries and fall back to the *proxy.config.http.cache.max_open_read_retries*, in case, they hit the bound.
