मुझे यकीन नहीं है कि संबंधित जीसी लॉग (नीचे) की व्याख्या कैसे करें। विशेष रूप से:
ढेर जीसी आमंत्रण के बाद = 31 (पूर्ण 3): इसका मतलब यह है वहाँ थे 31 नाबालिग जेंटलमैन कैडेट, और 3 पूर्ण जेंटलमैन कैडेट?
क्या कुल समय के कई लगातार लाइनों जिसके लिए आवेदन धागे और आवेदन समय बंद कर दिया गया चलाता है? क्या इन पंक्तियों में से प्रत्येक के साथ जुड़े समय टिकटों को प्राप्त करना संभव है?

"कुल समय के लिए आवेदन थ्रेड बंद कर दिए गए थे" संदेश द्वारा मुद्रित किया गया है: + प्रिंटजीसी एप्लीकेशनप्लेप्टाइम जीसी लॉगर नहीं है। इस कथन पर कोई टाइमस्टैम्प नहीं है (हालांकि आपको अभी भी बंद और समवर्ती समय का उपयोग करके टी = 0 पर वापस काम करने में सक्षम होना चाहिए)। आप ओपी में इसे देख सकते हैं क्योंकि जीसी कार्यक्रमों में समय और तारीख टिकट हैं। – Matt
